In a structure of a bridging electrode, the structure of a bridging electrode applied to a capacitive touchpad, the structure comprising: a substrate; a plurality of first electrode blocks disposed on the substrate and electrically connected together in series through a first wire; a plurality of second electrode blocks disposed on the substrate and respectively disposed on two sides of the first wire; and a bridging insulation unit, which is perpendicular to and disposed on the first wire and having a bridging groove; wherein the second electrode blocks connecting electrically together in series through the bridging insulation unit having a second wire.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A structure of a bridging electrode applied to a capacitive touchpad, the structure comprising: a substrate layer; a transparent electro-conductive layer disposed on at least one side of the substrate layer, wherein the transparent electro-conductive layer has a plurality of neighboring patterned blocks; an alignment film layer disposed on one side of the substrate layer and the transparent electro-conductive layer, wherein the alignment film layer has a plurality of bridging grooves, the plurality of bridging grooves crossing between the patterned blocks, a conductive wire disposed in the bridging grooves connecting two adjacent patterned blocks; and an electro-conductive layer disposed adjacent to the one side of the alignment film layer.
2. The structure according to claim 1 , further comprising a protection layer disposed on at least one side of the substrate layer.
3. The structure according to claim 2 , wherein the protection layer is an organic material layer, a photoresist layer, an anti-reflective (AR) layer, an anti-gloss (AG) layer or a combination thereof.
